Hi there! Currently I'm trying to run Monte Carlo sampling to test my circuit design. I'm trying to add mismatch to the resistors in my circuit. The resistors I used is from the analoglib. I write a res_model.h head file an include it in the model library in the setup panel in adel. I refer to the following links:

The content of the head file is

statistics {

    process {

        vary RH dist=gauss std=20k percent=no

        vary RL dist=gauss std=5k percent=no

    }

}

And the netlist file is

Then I run Monte Carlo sampling in ADEXL, but I receive the following ERRORs

Spectre simulator stopped due to following reasons:

Error found by spectre during circuit read-in.

Error found by spectre during circuit read-in.

ERROR (SFE-1703): "/home/jiangchenxin/Desktop/RRAM_work/res_model.h" 2: Wrong number of nodes . Port instance has 2 or 3 terminals

Resolve these errors and rerun simulation.

 

Which part did I make mistake? How should I add user defined mismatch to the parameters in the design? Thanks!!
